renaming his eyes {111e right hand button 12firefight-indicator 2 will be rendered operative, by pressing the left hand button 13 the left indicator 3 will be rcdered operative, and by pressing 5 both of the buttons 12 ously the. stop iiidieator' i 'wiil be rendered operative. The switch governed by the buttons 12 and 13 preterably comprises a walking beam 1 1 that is pivotally connected midway .itz-rends to a movable or slidable support 15,115; shown in Figure 1, the buttons 12 and 13 l'ieing mounted on the opposite ends of said walking beam. The beam 14 is provided with a conducting arm 16 interposed between two contacts 1'? and 18 arranged in the circuits of the right and left indicators, respectively, and the shiftable support 15 on which the walking beam 14 is pivotally mounted is provided with a conducting portion 19 that co-operatcs with a con wt arranged in the circuit of the op indies. or it. it contractile spring 16 is counse to the upper end of the conducting arm 16 of the walking beam so as to nopmally hold said arm out of engagement with the contacts 17 and 18 and also hold the conducting portion 19 on the walking beam support out of engagement with the contact 20. The beam 14 can be operated directly from the push buttons 12 and 13 at the ends of same or indirectly through. a suitable means that will. transmitmovement to said beam from suitable controlling devices. For example, as shown in Figure 2, controlling devices 12 and 13 on the steering wheel of the vehicle can be associated with pneumatic or hydraulic devices 21 and 22 in such a way as to cause the beam 1 to-move in a direction to close the circuit of the right indicator when the controlling device 12 is operated, move in a direction to close the circuit of the left indicator when the device 13 is operated, and move in a direction to close the circuit of the stop indicator when the devices 12 and 13 are operated simultaneously. Fig ure 8 illustrates another method of operating the beam 14 of the controlling switch consisting of controlling devices 12 and 13 on the steering wheel of the vehicle electrically connected with electro-magnets 21 and 22'" that actuate the beam 14 in such amanner that when the controlling device 12 is actuated the circuit oi? the right indicater will be closed, when the controlling device 13" is actuated the circuit of the left indicator will be closed and when the controlling devices 12* and 18" are actuated simultaneously the circuit of the stop indicatorwill be closed. In the various forms of my invention above referred to an electro-magnetic relay A is employed to automatically govern the operation of the ahead indicator, the Wind ings of" said magnet A being in series withand 13 simultanethe common return of the controlling circuits for the right, left and stop indicators. When the magnet of the relay A is energized its armature is actuated, thereby opening the circuit of the ahead indicator, and thus rendering the ahead indicator inoperative. The same result can be accomplished. in various other ways, however.

Having thus described my invention, what 1. claim as new and desire to secure by Letters Patent. is:

1. A cont-rolling switch for three electric circuits, comprising areciprocating sup port provided with a conducting portion and adapted to be moved towards and anay from a stationary contact, a. beam pivotally connected intermediate its ends to said support, a conducting arm on said beam arranged intermediate two stationary contacts, said beam being adapted to be rocked on its axis so as to move the conducting arm thereon into and out of engagement with the contacts between which it is interposed, and means for normally maintaining the conducting portion of said support and the conducting arm on said beam out of engagement with the contacts with which they co-operate.

2. A controlling switch for three electric circuits, comprising a reciprocating support provided with a conducting portion and adapted to be moved towards and away from astationary contact, a beam pivotally connected intermediate its ends to said support, a conducting arm on said beam arranged intermediate two stationary contacts, said beam being adapted to be rocked on its axis so as to move the conducting arm thereon into and out of engagement with the contacts between which it is interposed, and a spring arranged to exert pressure on said support and on the conducting arm of said beam so as to normally hold said conducting arm in a neutral position with relation to its co-operating contacts and to hold the conducting portion of said support in an inoperativeposition with relation to its co-operating contact.

3. A controlling switch for three electric circuits, comprising a reciprocating support provided with a conducting portion and adapted to be moved towards and away from a stationary contact, a beam pivotally connected intermediate its ends to said sup port, a conducting arm on said beam ar- ;ranged intermediate two stationary contacts, said beam being adapted to be rocked on its axis so as to move the conducting arm thereon into and out of engagement with the contacts between which it is interposed, and a contractile spring connected to the conducting arm on said beam, for the purpose described.
